The Lowdown

Alright folks, Rusty here. Let’s talk about what’s on offer at our local stretch, Kennebunk Beach.

Honestly, the next couple of weeks look like a bit of a flat spell. The waves we’ve got coming through are small, and the conditions aren't lining up to make anything worthwhile. We're staring down a long gap here with nothing worth paddling out for through the entire 16-day window. There are no good surf options in this outlook. The overall combined wave energy is weak, with values only reaching into double digits (57) at the start and barely touching a moderate 119 by late August, but even then the wave quality is just not there.

Water temp is sitting in the mid-60s°F with a anomaly of about 1°F, so pretty much what you’d expect for this time of year—nothing to write home about.

There is a slight tease on the morning of Friday, August 28th. We see a 3ft swell from ESE with a 8-second period, and the wind is glassy. The combined energy hits 119, so there’s some push there. But it’s still a sheltered beach break, and the "poor surf conditions" tag is a killer. It might look a bit bumpy and unshaped. If you’re absolutely desperate, maybe a dawny on a longboard could work, but don’t expect much.

For the rest of the period, it’s a whole lot of nothing. Small bump, onshore breezes, and weak energy. A few morning windows look clean with offshore or glassy wind, like Friday the 21st morning with 2ft and offshore wind, or Sunday the 23rd morning glassy with a tiny 2ft. But the swell is just too small and weak to hold any real form.

If you’re into kiting, some of those afternoons with a decent breeze and small chop might be more your thing, because for paddle surfing, it’s a write-off.

Keep the board in the car, but don’t get your hopes up. The forecasts can always change, but as it stands, we’re in a quiet stretch.

Rusty.

Information about the Kennebunk Beach Surf forecast

The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Kennebunk Beach is 17 km (11 miles) from Biddeford. If you plan a vacation in Maine, look for hotels and other accommodation in Biddeford. Biddeford has rooms for a wide range of budgets as well as car hire and transport links.
